Doctrine 2 vs Entity Framework Core: What are the differences?
Developers describe Doctrine 2 as "An object-relational mapper (ORM) for PHP 5.3.2+ that provides transparent persistence for PHP objects". Doctrine 2 sits on top of a powerful database abstraction layer (DBAL). One of its key features is the option to write database queries in a proprietary object oriented SQL dialect called Doctrine Query Language (DQL), inspired by Hibernates HQL. On the other hand, Entity Framework Core is detailed as "*Lightweight and cross-platform version of the popular Entity Framework *". It is a lightweight, extensible, open source and cross-platform version of the popular Entity Framework data access technology. It can serve as an object-relational mapper (O/RM), enabling .NET developers to work with a database using .NET objects, and eliminating the need for most of the data-access code they usually need to write.
Doctrine 2 and Entity Framework Core can be primarily classified as "Object Relational Mapper (ORM)" tools.
Entity Framework Core is an open source tool with 8.01K GitHub stars and 2.05K GitHub forks. Here's a link to Entity Framework Core's open source repository on GitHub.
